Openhab MQTT connect to AWS iOT core

Hi, I was looking for a tutorial to connect openhab 2.5 with MQTT to AWS IoT core. I have OH2.5 and MQTT installed on the RPI. Secondly I downloaded the AWS IoT SDK (with python) and connected the RPI to AWS IoT Core. I wonder now how I setup MQTT properly?

Many people use Mosquitto as an MQTT Broker For AWS to MWQTT you need to talk about that on their forums.

Apologies for the above badly-researched post which I have now deleted …
Based on some additional reading it looks like MQTT connections to AWS IoT require some capabilities that the OH MQTT binding may not yet support? So I guess I will have to hold on for a while.

Have a look to this thread Need to subscribe to MQTT messages from an external server. Do I need a broker? . The Mosquitto broker needs to be configured to act as a bridge.
